So I rode the 610 to work today for the first time in quite a while. I'd been comuting on my R1, but decided to start riding the Husky more. I get to work and hop off the bike, and noticed some oil dripping on the case just under the air filter. Upon closer inspection, I see that the oil is dripping from the air box/filter area. Anyone have any idea, why I would get oil coming from here? I did have one backfire that stalled the bike, while riding in this AM, could that have some how pushed oil up the TB and in to the air box? How would it have gotten past the rings if that was the case? Just grasping at straws here, any input appreciated. A little background on the bike. Bought last year from Heinen's. Haven't had any problems. It has around 1200mi odo right now.
The head vents crankcase fumes through a hose into the airbox. If you ride hard or overfill your oil, you will end up with engine oil in the airbox.
That's good to know. I think I just read on Rick Ramseys web page, that he was able to re-route both the crankcase and tranny breather and add a filter, but in saying that if that much oil comes out of the line when ridden hard that filter may be useless. I'll crack it open this weekend and have a look. Did you just leave yours connected?
The color is a bluish green, and actually looks very clean. It's been about 600 mi since my last oil change so I figure it would be quite a bit darker. I'll have to peep at the window in a little bit to see if the oil still has any color to it. I have never personally oiled the filter, so whatever oil is on there is there from the factory, I would have imagined most would have dissipated by now.
Blue/green and tacky, that's air filter oil. To avoid an over-oiled air filter, I use a trick I learned here on the forum. I bought a second air filter. I oil it up pretty liberally and put it in a ziploc freezer bag. Then I hang the bag up on the wall in my garage. Over time, while I'm riding with the other filter in place, the excess oil drips down to the bottom of the bag. When it's time to clean my air filter, I clean and oil the one that's on the bike, then swap them. If you do that, you always have a filter on hand, clean and ready to go. You also cut down on the excess oil collecting inside your airbox.
Thanks for the tip J. I'll keep an eye on the air box, and try your method. This being my first dual sport/MX type bike, I've never oiled a filter on any of my bikes. So this is all new to me. I appreciate the feedback from everyone.
I do the same although I keep two spare filters for each bike. Then I only clean filters once a year but do a batch of six filters at a time. Makes it so much easier and you'll find yourself swapping filters when really needed instead of postponing due to the dirty cleaning/oiling job. One note some filter oils have a alcohol base that needs to evaporate before use. For those oils make sure after oiling your filter you air it out overnight before putting it in the ziploc bag. Instead of ~$50 at the dealer buy your extra 610/630 filters under the Twin Air p/n: 155506. Only $31 at BikeBandit after 10% AMA discount. _
Only cure I found is wad up a paper towel and stuff it under the air box. Take it out when you go riding..... It's usually filter oil anyway...
